To all whom it may concern:

'Be it'kriown that l, llowaun M. Cnnuirnn, a citizen of the United States, `residing at Dallas, in the county of Gaston and State of North Carolina, have Vinvented certain new and useful Improvements in Metallic Shingles, ot' which the followingr is a speci-' fication. f

My invention relates to metallic shingles and its object is to provide an article of this kind having means by which it'is adapted to be firmly locked to adjoining shingles, and having a spring lock seam that will prevent the entrance of water, and also having an effective means for carrying oli'` any Water that may overfiow the seam. To these ends. my invention is embodied in preferable form' `in the article hereinafter 'described and illustrated in the accompanying drawings.

1n these drawings, Figure 1 is a plan view showing two whole shingles and a half shingle in place; Fig. 2, a section through the lock jointon line of Fig. 1; Fig. 3, a section on line i/-wg/ of Fig. 1 showing the overlapping ends, and Fig. 4 a detail section of modified form ot lock joint.

Referring to the drawings and particularly to Figs. 1 to 3, inclusive, 1 is a metal shingle and 2 is a transverse ridge near the upper end withwvhich engages the bent lower end' '3 of the adjacent shin le above.v

The extremity of the upper end o vthe shingle is curved up at et so as to Contact against the under surface of the shingle above it and form a close joint.

Extending,longitudinally of the shingle alongthe right hand edge thereot` is a raised rail member of abouty five-sixteenths of an inch in height and having a rising, substantia-ily vertical wall 5, a locking portion (l extending back over the shingle, an upper section 7 doubled over the part 6 and an outside descending wall section 8. From the wall section 8 the shingle is extended horizontally to toi-m a nailing flange 9 which is adapted to-be'fastened to the sheeting niider the shingle. The wall 8 is carried slightly below the level of the flat body ot' the shingle as shown at l() and bent upward to a sharp spring ridge 11, t'oimiug` a gutter 12 which 'is adapted to receive and carry olf any overflow of water passing over the rail and between the joint. The left hand edge of each shingle is bent upwardly to form a hook comprising a rising, substantially vei'- tical wal'l 13, a substantially horizontal part 1st over the adjoining shingle and a downwardly extending angular lip 15. This hook member is adapted to lock over thc rail member of the adjoining sliingle'and the lower extremity ot the vlip 15 beais against the surface of the said adjoining shingle so as to close the joint. The inner locking mem-f ber consisting of the returned rail member gives a spring lock action against the outer lhook member that will ettectually close the j oint against leaking. The overlapping shingle also bears against the ridge 11 'ob-- taining a spring locking closure at lthis point.

In Fig. 4 is shown a modification in which a curved, raised hook member 16 provided with a returned horizontal lip 17 is adapted to interlock with a curved iail member 18 forming the inner lock.

The lshingles embodying my invention are adapted to be applied to the roof by arranging them in vertical lilies running from the eaves to the comb of the roof .with continuous vertical joints and with broken horizontal joints. Thus, starting from the eave the shingles are placed in vertical alinenient to the root with each shingle over-I lapping the one below it. At the' nextverl tical line of shingles, the one adjoining the eave would be a half shingle to which acomplete shingle would be jointed above it and so on, so that thejoint is broken horizontally.

l hereby disclaim the raised portions orV ribs shown on the body of the shingle as the same form no part of my invention.`

Having thus described my invention, what l claim is A metallic shingle having a joint lock4 member at one edge thereof consisting of a wall rising above the surface of the body ot' the shingle and bent back over the body of the. shingle to provide a hoolc engaging ortion and then doubled upon itselt` to o ose said portion and At'oi'm a spring locking member and carried outwardly -and then downwardly below the level of the body of the shingle and having a substantially horizontal nailing' flange extending t'rorn the end ot' the Adownwardly extending part and provided with a ridge projecting upwardly into line with the lower surface of the shingle body to bear with spring pressureagainst the adjoining shingle, said @ange being spaced 'from the adjoining shingle between the lower end and said ridge to forni a gutter and being continued beyond said 10 up to the bases raga-inst ridge to form a. naing portion, said rst shingie at its opposite edge having :i coml pleinentmy membei; consisting of a raised hook member passing over the first described -membet' ofen adjoining shingle a'nd engagreturned portion and bearing the surface of the body of the shingle, the main body portions of the adjoining shingles extending in the same plane of said members and seid ing the plane lying below the top of the members and above the nailing and gutter ange, said members being heid together by spring action, substantially as described.

In testimony whereof l have ziixed my 15
